Simplify run level decoding:
...
- remove unneeded vlc code < 0 check
- reorder vlc code handling so that the unlikely escape decoding
part comes last
- move overflow check out of the decode loop
- branchless sign conversion

VC-1/WMV3 decoding: don't clear blocks unless they're actually used.

~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.
...
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).
